Hello
The fault to this Trinitron TV is loose soldering ofcourse. Check all the soldering points at the video output card, which can be located at the base of the picture tube. Normally the components fitted on this board will heat up while working, and repeated heating and cooling will make the solder terminals of the componets to get loose contacted. Just pull out the CRT base board from the CRT causiously without make a damage to picture tube pins. Look for any loose solderings at this board. It is quite difficult to detect these loose solder points as some of them will be microscoppicaly small and can be seen with the help of a magnifying glass. Just do what we do at service table. Just resolder all the suspected solder points by applying a little more solder, without making any solder bridge short between adjecent solder terminals. In most cases, nearly 85%, the fault will be cleared out with this process. Check the plug in connection wire [comes from main board to picture tube base board] for any loose connection. Just pull it out from the main board, and reinsert it for at least two times. If any loose connections to this wire connection, this will clear out it. OK.

Connect cables:
Connect yellow to yellow (dvd player to TV)
Connect white to white (dvd player to TV)
Power on DVD and TV and insert a DVD into the player, press PLAY.
Use your TV remote to select the proper input:
Your remote should have a button like INPUT SELECT or Video, keep pressing until you see the DVD players output.

When a TV hasn't digital tuner, it's necessary to add it a digital to analog channels converter box, but your TV already has digital tuner, you can switch between digital and analog tuning by pressing the digital/analog botton on the remote control.

There is a service menu adjustment. I have seen several of these sets with bad components in the horizontal width control circuit. maybe your other set has a width problem. put both on the same channel. like cnn with the ticker on the bottom. what is the difference in size?
the width adj. procedure is: with the set off. use the remote, enter. MENU>5>VOL+>POWER . the set will come on in the service mode. then with the menu adj. buttons you can step threw the service menu to H.WIDTH adj. until full picture. also VERT. HEIGHT. when you are done adjusting make sure you press the mute button and watch the word WRITE flash from green to red or you won't save your adjustments.

check the crt board replace transistor

If you take a working remote, point it at the TV and hit "3", then "ENTER", does the set go to channel 3?
